core: add new domain join logic

[undefined-moe]

引入 【加入域】 概念使其更符合直觉，同时提供退出域功能

• [ ] 是否应当将未加入域的用户作为 guest 权限组管理？

[pandadtdyy]

我认为应当允许用户设置为私密域/公开域（guest/default）

[undefined-moe]

guest: N/A default: PERM_VIEW 则普通用户访问跳转到 /domain/join，未登录用户跳转登录 guest: PERM_VIEW, default: PERM_VIEW 则普通用户和未登录用户均可直接访问

[undefined-moe]

guest: PERM_VIEW, default: PERM_VIEW, PERM_SUBMIT_PROBLEM 旧逻辑：访客 (guest) 可注册后 (default) 提交题目，成为域成员 (default) 新逻辑：访客 (guest) 可注册后 (guest) 无法提交题目 （如何引导？）

对主域的管理： 若新用户注册后自动加入 system，则域内榜单会出现大量无操作用户； 若不自动加入，则注册后用户仍需前往 /domain/join 手动完成加入域操作；

Walkthrough

The pull request introduces a wide range of configuration, dependency, and API improvements across many modules. Changes include new configuration files and updated ignore rules, updated build and installation scripts with modern TypeScript and Yarn settings, significant refactors in the judge‐ and UI–related modules, new ESLint and schema configurations, and migration enhancements enforcing lock checks and BigInt pagination. Several global assignments have been removed in favor of context–based injections, and new features (e.g. Kattis checker support, OnlyOffice i18n messages, resolver pages for onsite toolkits) have been added across both backend and frontend code.

Changes

Build & Installation Scripts build/prepare.js, build/publish.ts, flake.nix install/install.sh, install/install.ts, root package.json	Upgraded TypeScript compiler options, Yarn version, publish tag and versioning logic; added a new Nix flake for development; improved install scripts with decompression, crypto, and enhanced warning checks; dependency updates.
ESLint & Framework Configs framework/eslint-config/*, framework/framework/*	Added new ESLint plugins and extensions; enhanced handler, decorators, interface, and serializer functions with better type safety and context–injection.
Judge Module Enhancements packages/hydrojudge/**/*	Major refactors with breaking API changes: new checker methods (including Kattis and communication), improved file handling, refined versioning logic, and extensive TypeScript generics updates.
Domain, GeoIP & Registration Handlers packages/geoip/*, packages/hydrooj/src/handler/*	Refactored constructors, error handling, event mapping, and dependency injection for domains, discussions, contests, and user registration.
Metrics & Migration packages/prom-client/**/*, packages/migrate/**/*	Integrated Schema-based settings for metrics; migration scripts now enforce lock mechanisms and use BigInt for pagination; version and dependency updates.
OnlyOffice Integration packages/onlyoffice/**/*	Enhanced error handling and i18n support; version bumped; removed unneeded devDependencies.

Poem

I’m a bunny hopping through the code fields,
Digging deep in configs and builds with zeal.
I nibble on changes—new checkers and locks,
Fancy UI and API upgrades in lots.
With ears perked high and a joyful heart,
I celebrate each update with a happy little start!
Keep on hopping, dear coder, for the changes are art!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
